Telkom / to cancel my account with telkom

I am trying to close my account with telkom. I done everything they require in NOV or 2018. I phone the just to extend it for me another month and closed it end of Dec which did not happen. I phone them a couple of time to do this. Then they say to me they cannot close it because I wanted to keep my mail need to phone another department, they need to split it. when I phone them they told it need 1st to be closed. So I went from one department to another department every time. Then the other department Account department said I must just tell them to closed it. They do not know what they are talking about This is the department to close your account Which I did This is already February month Still is not happening. They also said someone will phone when they escalate it Nobody ever phone me. I am so fed up with them. Then they overcharge me with my monthly bill payment This I am struckel with since August 2018 also not sorted out. I do not know what is going on there in that company Hope you people can do something for me. I am a pensioner and cannot afford to keep phoning and paying the bill. Thank you
